Prompt direction for anyone who wants to try the concept:
Create a vertical 4:5 cinematic cyber-fantasy illustration of a colossal dark biomechanical mecha guardian standing inside a ruined techno-gothic cathedral. Give it layered obsidian-black armor, a narrow cyan visor, a violet-cyan chest core, believable mechanical joints, and a clean monumental silhouette. Place broken segmented halo rings behind its upper body and give it one enormous rune greatsword planted into the fractured floor. Add one small cloaked figure in the foreground for scale. Use towering gothic arches, damaged luminous windows, rubble, sparks, atmospheric haze, and controlled cyan and magenta-violet lighting. Keep the armor readable through sharp rim light and material contrast. Avoid extra limbs, malformed hands, floating armor, warped weapon geometry, random text, excessive neon, and clutter that weakens the focal subject.
